Auckland is forecast to hit 20C, with clear skies and light winds for most of the day - a similar story over most of the North Island.

The South Island is even joining the fine weather party today, and Christchurch tops the main centres on 20C with light winds. Nelson and Dunedin are also in for mild, fine weather today.

From dry to wet. Compare the expected daily rainfall for tomorrow to what is expected at the weekend. Note that there is reasonable uncertainty in the models still regarding the weekend, and the location of the heaviest falls may vary from here. https://t.co/Yjbq0jfCz1 ^TA pic.twitter.com/XoYMJ64bOP
